add-skill skillA
add-skill is agent-read markdown (skill) from openhands/extensions: Import an existing skill from a GitHub repository URL into the current workspace. Use only when the user provides or references a GitHub URL/repo to fetch from (e.g., `/add-skill https://github.com/OpenHands/extensions/tree/main/skills/codereview` or "add the codereview skill from https://github.com/OpenHands/extensions/"). Handles fetching the skill files and placing them in .agents/skills/. This does not author new skills — to create a new skill from scratch (no source URL), use the skill-crea.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Add Skill Import skills from GitHub repositories into the current workspace. ## Workflow When a user requests to add a skill from a GitHub URL: 1. **Parse the URL** to extract repository owner, name, and skill path 2. **Fetch the skill** using the bundled script: ```bash python3 <this-skill-path>/scripts/fetch_skill.py "<github-url>" "<workspace-path>" ``` 3. **Verify** that SKILL.md exists in the destination 4. **Inform the user** the skill is now available ## URL Formats Supported - `https://github.com/owner/repo/tree/main/path/to/skill` - `https://github.com/owner/repo/skill-name` - `github.com/owner/repo/skill-name` - `owner/repo/skill-name` (shorthand) ## Example User: `/add-skill https://github.com/OpenHands/extensions/tree/main/skills/codereview` ```bash # Run the fetch script python3 scripts/fetch_skill.py "https://github.com/OpenHands/extensions/tree/main/skills/codereview" "/path/to/workspace" # Verify installation ls /path/to/workspace/.agents/skills/codereview/SKILL.md ``` On Windows, use `python` if `python3` is not available and verify with PowerShell, for example: `Test-Path C:\path\to\workspace\.agents\skills\codereview\SKILL.md`. …
